In the table below I'm trying to work how trend is being produced but I can't figure it out.
I have found how to find the moving average =AVERAGE(C2:C5)
I've tried a few methods using the trend function but I really don't understand what I'm doing. how its being calculated by looking at the table?
this User Defined Function (UDF) would operate on any specified data (ignoring blanks) over a range. Inputs to the UDF are range and period.

View 6 Replies View RelatedI have a set of data in column A consisting of over 1200 numeric values. The problem is that there are some blank cells in this column:
Colums A data:120, blank, 135, blank, etc
I need to calaculate the average for the first 25 data and then claculate the average for the next 25 data set dropping the first 5 and adding new consecutive 5 data ignoring all the bank cells!, so if the first statemnet is : averagre (a1:a24), the second statmnet should read (a6:a:29) not counting the blank cells. I don't know what array formula can be used to do this job for me.
I am trying to do a moving average and running into an issue with the count part of the formula.
Column C (C2 to C54) has the numbers I need to average.
Average is based on last 5 weeks.
My issue is that C23 is blank as we had no data for that week.
Currently the formula is counting 25 entries between C2:C27, there should be 26.
My average should be 31 but I am getting 33.
This is the formula I am using :
=AVERAGE(OFFSET(C2,COUNT($C$2:$C$54)-5,0,5,1))
I have tried using different Counta and ISnumber still not working
I would rather use a formulas then VB code.
I have done quite a bit of looking on Google and looked over the posts in this forum, however, I can't find an example Excel worksheet for a linear weighted moving average.
The data set I am applying this to has 180 data points and the linear weights should extend back over the last 30 points.
I am using the built in moving average function to calculate the moving average of a set of numbers. There are a few things that i would like to do.
First i would like to have the last result displayed in a single cell. Then next to that cell i would like to have a cell that would specify the period of the moving average. I would like to be able to change the period in that cell and have that change it in the actual function. And finally i would like to have the moving average in a chart that would also change its period once that is changed in the respective cell. I realize that this might need some VB coding which i am currently learning.
I would like to calculate the moving average for the first ten rows in a column where each new entry is added to the cell above the last entry.
For example
A5, 2
A6, 3
A7, 4
A8, 5
A9, 6
A10, 7
A11, 8
A12, 9
A13, 10
A14, 11
A15, 12
Therefore in the current list the average is AVERAGE(A5:A14)=6.5.
The next entry added to the list will be in cell A4 making the list look like this
A4, 1
A5, 2
A6, 3
A7, 4
A8, 5
A9, 6
A10, 7
A11, 8
A12, 9
A13, 10
A14, 11
A15, 12
The average of the first 10 cells is now AVERAGE(A4.A13) = 5.5
I would like to enter one formula in say cell A1 that will calculate the moving average in the first ten cells each time a new entry is added. Naturally as needed, new rows are added below cell A1. I hope my problem is clear.
as I have been unable to solve it myself. I have tried using offset but have been unable to resolve the issue.
I have a column of data that contains various blank cells where no data was measured. In the adjacent column I want to take the moving average of the last 4 data points including the most recent entry. My problem is i do not know how to handle blank cells where there was no data. I need it to average the last four in the column where data acutally exists. I am ok with using helper cells if needed and I am not worried about the first four results at this time.
Example data
A..................B
15
50
25
20................55
Blank............55
30................31.25
35................27.5
blank............27.5
blank............27.5
15................25
10................22.5
15................18.75
40................20
blank.............20
The following code works fine if the data is sorted from oldest to newest. I need for it to work when the data is sorted from newest to oldest. For this to work, I would need a change that works something like this: "total1 = total1 + close_(a, 1) * a" would be "total1 = total1 + close_(a, 1) * b" with "b" incremented in the opposite direction of "a". I code very infrequently & have tried a lot of different things, searched the Internet, etc. all to no avail.
For instance, with "close" data in column "I", the data sorted as follows works with the formula
"=WMA(OFFSET(I2,0,0,9,1) )" to correctly return "791.50", but the opposite sort returns the wrong number.
The correct calculation is: (807.19*9+798.38*8+793.81*7+793.06*6+776.28*5+769.48*4+773.2*3+789.01*2+793.87*1)/(9+8+7+6+5+4+3+2+1).

how do I perform calculations on the last x non-blank instances in a data range?
for example, let's say I have a spreadsheet of 5 baseball players' batting averages (rows are team game number played, columns are at bats and hits for each player). I want to see how each player has performed in their last 10 games played, but some players have not played in every game. If I just use the sum function for the last 10 cells, I won't get the correct information for any player that has missed one or more of the last 10 games.
Currently i have a spreadsheet with realtime data feeds from Bloomberg (or reuters). What i would like to do is:
a. Fill a vector/column of data values every minute until we have 30 observations i.e. from 9.00am till 9.30pm
b. This will then allow me to calculate a moving average of the last 30 (1 minute) observations.
c. At 9.31am, the 9.00am value drops out of the column and is replaced by the observation at 9.31am. This results in a constantly updating column of the last 30 minute observations and will allow me to have a realtime moving average.
I have a worksheet that has all weekday dates in column 1 and values in column 2. I want to create a 30-day moving average based on the last (non-zero) value in the column 2.
Since every month has a different amount of days, I want it to search the date that has the last value (since I don't get a chance to update it daily) and go back thirsty days from that date and give an average of all the column 2 values skipping and values that are null or zero.
I have a pivot that includes customer data and I need to create an average for each row based on the first populated column for each customer. After one month of units appears for the customer, I need to calculate the average going forward, and if there are blanks after that they should be treated as 0 in the average. Below is an example of my description of the pivot.
Jan Feb Mar Apr
Customer #1 1 1 3
Customer #2 1 3
Customer #3 2 2
So, the average for customer #1 would be calculated from Column B to Column E, and factor column D as a 0 in that calculation. Customer 2's average would start in Column C and go to Column E, and factor column E as a 0 in that calculation. Customer 3's average would start in column D to column E.
I have a spreadsheet which is linked to other spreadsheets. When I use "find and replace" on this spreadsheet, it causes one of my linked cells to move down one row. Why does it do this? This particular cell has nothing to do with the "find and replace" option.
I have no idea how to stop this from moving this cell down.
I have an excel work book with 6 tabs. I would like to have Excel move an entire row from one tab to another tab (removing the row and inserting it in the other tab). I.e. Example I have a tab with items that are marked as "Open Actions" so if I were to change the drop down to close. Excel would move that entire row of actions to the tab with the "closed actions" and insert into the next available row. Now if someone were to come back at a later date say no it should be reopened than I would change the drop down to open and excel would move that row back to the open actions tab into next available row. I tried a PIVOT table and no good I played with few macro and not.
View 5 Replies View RelatedI have 3 excel sheets (A,B and C) linked to a master sheet (X). In each sheet (A,B and C), people enter unique idetifier in first column, its type (mr, ab, J) in the second column, start date in the third column and finish date in the fourth column. At the end of every week, i subtract each start date from the finish date and get the number of days spent for each unique idetifier (column N). I preiously posted a thread (Calculate difference between dates excluding weekends) to inquire about how to calculate the difference between finish date and start date and exclude the weekends. I received some nice solutions, but none has worked as the start date cane be weekend as well.
My second and major query is once i have the difference in weekedays for each unique identifier in all the three sheets, I want to calcuate the average of each identifier type (mr, ab and J) in the master sheet. In the master sheet, i have used sumproduct to calculate the average of each idetifier type from column N for each sheet. That means i have a column for A sheet, subdivided into three types, which include the average. I am using sumproduct for this. Once this is done for each sheet type, i need a final colum in the master sheet that calculates average of all mr from A, B and C together, and similarly for ab and J. The problem here is if i combine all the sumproduct formula, i am not gettng the right answer.
My formula looks like SUMPRODUCT((SheetA!$E$5:$E$40="mr")*(SheetA!$M$5:$M$40)) for all mr in sheet A. I then divide this by SUMPRODUCT((SheetA!$E$5:$E$40="mr")*(SheetA!$M$5:$M$40<>"")) to get the average of all mrs in sheet A. I do the same for sheet B and sheet C for all three identifier types. Now i want to combine the formula for all sheets together under mr, Ab and J. I thought the following should work ((SUMPRODUCT((SheetA!$E$5:$E$40="mr")*(SheetA!$M$5:$M$40))+(SUMPRODUCT((SheetB!$E$5:$E$40="mr")*(She etB!$M$5:$M$40))+(SUMPRODUCT((SheetC!$E$5:$E$40="mr")*(SheetC!$M$5:$M$40)))/((SUMPRODUCT((SheetA!$E$5:$E$40="mr")*(SheetA!$M$5:$M$40<>""))+((SUMPRODUCT((SheetB!$E$5:$E$40="mr") *(SheetB!$M$5:$M$40<>""))+((SUMPRODUCT((SheetC!$E$5:$E$40="mr")*(SheetC!$M$5:$M$40<>""))).....
But this is giving me wrong value. It is working fine when done for individual sheets, but when combined for all three sheets together, the value is wrong.
Column B: The day of the week that the date is, Sunday, Monday, etc.
Column C: Every date in 2008
Column D: my data (the number to be averaged)
What I need the formula to do:
Look in Column B for every instance of "Sunday", and count them up (they count only if the data in column D is not 0) and use that number to average the number in column D
So if I have 52 Sundays and we are only 4 weeks into the year and the 4 data points are 50, 100, 75, 25. The average will be 62.5 instead of 4.8 (divided by 52).
I am trying to figure out how to take the average of the last 4 "non-zero" numbers in a series of values.
The sheet looks something like this, numbers are all in one row:
7 , 7 , 7 , 7 , Total = 28 , 8 , 8 , 8 , 8 , Total = 32 , 0 , 0 , 0 , 0 , Total = 0 , 8 , 8 , 8 , 8 , Total = 32 , 7 , 7 , 7 , 7 , Total = 28 , 8 , 8 , 8 , 8 , Total = 32 , 0 , 0 , 0 , 0 , Total = 0 , 8 , 8 , 8 , 8 , Total = 32
I'm looking for a formula that will look at all the last few totals (starting from the end) and take an average of the last 4 totals that were > 0. In this case it would average {32, 32, 28, 32} ignoring the 0 total.
Attached Dummy file. I would like to be able to get the average time spent on a process for the day recorded on the "Results" tab. I have posted the answers it should be on the Results tab, which was done manually. I would like the file to do it on it's own. On the individual's tab, the time and instances will be recorded for each job. I believe I am close, and the only thing I need is the Results page to be able to return the desired results. Ranges varies day-to-day, and I think (maybe), I can figure out the dynamic range settings.
I would like to avoid creating a helper column for each set, because then I would be dependent on the person expanding on this. I am also avoiding Pivot Tables, I understand it, but not the ones that needs it. This will have about 15 tabs for employees, and could be possible that more or less will happen, depending on workload. This will continue to be manual for now.
I have a total in F16 that i need to find an average of.
The range is set from f4 - f15 (12 months) and need to find the running average per month. but as we only have done 5 months of the year so far that is the only average required (F16/5).

In column A is the staff name, column B is the start date, column C is the end date and column D is the difference.
I need to find the average number days for task completed for each staff for the week. I need a formula that will look for a particular staff name in column A ( which appears many time randomly in column A for each day of the week) and calculate the average days for the total task completed for the week.
Let's say I had the following data ...
47
50
50
50
44
50
46
50
Basically, I have 4 numbers, out of 50, as seen above...I want it so the last number (46 in this case) is special; what I mean by that is I want the following conditions to be met.
--If the special number is the lowest, just take the average of the four numbers, and divide it by 50
--If there is a (are) number(s) lower than the special number, then I want it to locate the smallest
---The smallest number should then be "replaced" by the special number (for calculations purposes only, not in the actual table)
So, in this case, since the special number (46) is not the lowest, excel would locate the lowest number (44), and calculate the average of 47, 50, 46, and 46 (the 44 was replaced by 46).
